Synstax

Check your supplement stack before you take it.

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 8 June 2026; the live site may have changed since.

Synstax has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, analytics without a consent banner, and incomplete email security.

Launched on Hacker News on June 8, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 7 months before launch. Our crawler found 5 technologies on this site, covering analytics, CDN, web fonts, and mobile. The stack includes Apple App Store, Cloudflare, and Google Analytics.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
